Surgical Approach for Suprasellar Meningiomas Based on Attachment-Single-Surgeon Experience

Suprasellar meningiomas (SMs) can originate from midline or paramedian dura. Complexity of surgery and visual outcome depend on the attachment of SM. Conventional surgery for SM was ipsilateral to the visual deficit. We report our experience of surgical management of SM after choosing a surgical approach based on the attachment of the SM.

Sixty consecutive patients who underwent surgery for SM between January 2016 and January 2022 formed the study population. In patients with SM attached to the midline, the surgical approach was ipsilateral to the side of vision loss. In contrast, in those with a paramedian attachment, the approach was contralateral. Outcome variables included extent of resection achieved, recurrence, and assessment for visual acuity and fields, done at 3 months and 6 months after surgery and every year subsequently.

The average age of the study population was 49.99 ± 13.38 (13-74) years with 23 (38.3%) men. Surgery for SM was done via the ipsilateral approach in 18 (30.0%) and the contralateral approach in 42 (70.0%) patients. The average preoperative visual impairment scale score was 54.68 ± 37.55. Gross total resection was achieved in 58 (96.7%) patients. The average duration of follow-up was 3 years, and at latest follow-up, improvement in vision was reported in 46 (76.6%) patients.

In patients with SM undergoing surgical resection, opting for an ipsilateral approach when the SM had a midline attachment and a contralateral approach if the SM had a paramedian attachment may ensure greater resection of the lesion and better clinical outcomes. Our findings need validation in larger, randomized studies.
